BORING INIPLEMENT.

Specification of Letters Patent.

Patented Nov. 20, 1906.

To qll/Z whom, t rnd/y concern.-

Be it known that we, JEFFERSON F. PIERCE and WILLARD G. PIERCE, citizens of the United States, residing at Tampa, in the county of Hillsboro and State of Florida, have invented a new and useful Boring Implement, of which the following is a specification.

This invention relates to improvements in implements ada ted for boring or drilling in localities diflicu t of access, and has for its object toim rove the construction and increase the e llciency of devices of this character.

With these and other objects in view, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that various c 1an es in the form, proportion, and minor detai s of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention within the scope of the a pended claims.

In the drawings, Figure 1 1s a longitudinal sectional elevation of the improved implement. Fig. 2 is a sectional view, enlarged, on the line 2 2 of Fig. 1. Fig. 3 is a transverse section, enlarged, on the line 3 3 of Fig. 1.

In the improved device is comprised a tubular casing 10, internally threaded at the ends and with one portion extending at an angle to the other portion preferably at about forty-five degrees.

Fitting into one of the threaded ends of the casing 10, which for the purpose of this description is referred to as the forward portion, is a threaded tubular sleeve 1 1, havin a bearing 12 at the outer end, and likewise tting into the other threaded end of the casing, which for the purpose of this description is re erred to as the rear portion, is a similar threaded tubular sleeve'13, having a bearing 14 at the outer end.

Journaled in the sleeve 11 is a bit or drill socket 15, in which the boring implement, such as an augur 16, is secured by a set-Screw 17 or other suitable means. Journaled in the sleeve 13 is a socket member 18 forfreceiving an operating-stock 19, preferably tubular, and secured to the socket, as by a rivet 20. The inner ends of the sleeve 15 and 18 are provided, respectively, with interengaging bevel-gears 21 22, operating within the casing 10. By this sim le arrangement when the stock 19 is rotate the motion will be communicated to the bit or drill 16, as will be obvious.

Jam-nuts 23 24 will be applied to the threaded sleeves 11 and 13 and bearing upon the opposite ends of the casing 10 to prevent accidental displacement or the loosening of the sleeves when in use. The sleeves 11 and 13 being threaded in the casing 1() are easily adjustable longitudinally of the angularlydisposed ends of the same, and thus provide a simple means for adjusting the gears 21 22 and taking up wear as it occurs, and thus keeping the gears in working order and preventing rattling. Whe'n' the adjustments have been accomplished, the jam-nuts 23 24 enable the adjustments to be maintained, as will be obvious.

Surrounding the stock portion 19 of the implement is a tubular shield 25, engaging the bearing 14 at one end and with an internal collar 26 at the other end for supporting the, stock rotatively, the stock having a square end 27, protruding beyond the shield for receiving an ordinary brace or other implement for operating the stock.

The implement is preferably provided with supporting means consisting of a U-shaped member 28, bent at the center at an angle to the longitudinal plane of the sides or arms and bearing beneath the shield 25 opposite the rear bearing 14 and clamped thereto by a bolt 29. The spaced arms of the member 28 are also coupled by a strap 30, formed from a single piece and enclasping the forward bearing 12 of the sleeve 11 and the spaced sides of the member 28 `and coupled at their ends by plates 31 32 and rivets 33 34. The strap-brace is also clamped in position by bolts 35, 36, and 37. The supporting member 28 is preferably formed from a section of gas-pipingflattened centrally, where it is bent to engage the shield 25, as shown. The spaced sides or arms of the member 28 are parallel to each other and also spaced from and parallel to the longitudinal plane of the sleeve 11 and its bit-socket 15 and bit or other implement held therebyand is de- IOO IOS

signed to bear u on the structure in which the boring or dril ing is to be made, and thus support and guide the boring or drilling implement.

The device may be employed in many localities and for many purposes, but is more particularly adapted for boring in wood in localities inaccessible to an ordinary handbrace-as, for instance, in boring transversely through the joists in buildings when installing electric wiring-and for the purvided with a tubular shield 43 and bearingcollars 44 45 and coupled to the shield 25 by a `clamp-sleeve 46, the latter provided with clamp-bolts 47, as shown lin Fig. 3. By this means the operating-stock may be extended to any required length when required.

A screw-plug 48 is tapped into the casing 10, as shown in Fig. 1, to provide means for vinserting a lubricant for the gears 21 22 and other moving parts.

We claim- A 1. In an implement of the class described, a tubular casing internally threaded at the ends `and with the forward portion disposed at an angle to the rear portion, a tubular sleeve externally threaded and adjustably engaging the forward portion of said casing,- a tubular sleeve externally threaded and adjustably engaging the rear portion of said casing, a socket member journaled in said forward sleeve and having a cavity for receiving a boring implement, a socket member journaled'in the rear sleeve and having a cavity extending longitudinally therein, a stock engaging said longitudinal cavity and rigidlyconnected therein and provided at the rear end with means for applying a rotative implement, the inner ends of said socket members provided with interengaging bevelgears. l

2. In an implement of the class described, a tubular casing internally threaded at the ends and with the forward portion disposed at an angle to the rear portion, a tubular sleeve externally threaded and adjustably engaging the forward `portion of said casing, and Vprovided with a bearing in advance of the sleeve, a tubular sleeve externally threaded and adjustably engaging the rear portion of said casing and provided with a bearing in the rear of the sleeve, a socket member journaled in said forward sleeve vand having 'a cavity for receiving a boring implement, a socket member journaled in the rear sleeve and havingv a cavity extending longitudinally therein, a stock engaging said longitudinal cavity and rigidly connected therein and provided at the rear end with means for applying a rotative implement, the inner ends of said socket members having interengaging gears, a supporting-frame clamped to the bearing of said rearward portion of the casing and with spaced sides extending parallel to the forward portion of the casing, and a brace clamped to the bearing of the forward portion of the casing and connected at the ends to the spaced sides of said frame.
